TRY-SQUARE.

SPECIFICATION forming part of Letters Patent N 0. 710,891, dated October'7, 1902.

Application filed January 24, 1902. Serial No. 91,123. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL Russ PUGH, a citizen of the United States,residing at Houston,in the county of Harris and State of Texas,

have invented new and useful Improvements in Try-Squares, of which thefollowing is a specification.

This invention relates to try-squares; and the aim of the presentimprovement is to provide means for continuing a scribe or mark aroundthe edge of a board or piece of timber to correspond to a mainindication accurately on both sides without changing the position of thesquare, and, further, to have the main blade of the square constructedfor gaging or ruling by the provision therein of apertures to receivethe point of a pencil or other marking device. I

The invention consists in the construction and arrangement of theseveral parts, which will be hereinafter more fully described andclaimed.

1n the drawings, Figure 1 is a perspective view of a try-squareembodying the features of the invention. Fig. 2 is an edge elevation ofthe same in position for use. Fig. 3 is a plan view of the improvedsquare in such position as to adapt it for marking purposes,particularly in drawing bevel-lines for miters and the like.

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The numeral 1 designates the stock, having the usual blade 2 securedtherein, which is provided along one edge with a series of apertures 3,from which scale-marks 4 project. These scale-marks and the aperturesmay be at any distance apart in accordance with the divisions, and thefunction of the apertures is to receive the point ofia pencil or othermarking device for the purpose of accurately defining a mark on the woodor material on which the square is used relatively to the adjacentbearing edge of the stock 1. By this means it will be seen that thestock and blade can be moved over the material and the blade heldpositively in position on the material by pressing the stock against theside edge of such material, and thereby insure the formation of astraight mark. The blade 2 is also provided with a series ofobliquely-arranged apertures 5, through which a pencil-point or othermarking device is adapted to be projected to lay off bevel or miterlines, and after theseindications have been applied to the materialoperated upon the blade 2 or a portion of the device which will behereinafter set forth may be used for connecting the marks appliedthrough such use of the said apertures 5.

The improved square also, includes an auxiliary blade 6, which isdisposed in a plane at right angles to the blade 2 and has an angularshank 7, bearing upon said blade 2 within the extremity of the stock 1,as clearly shown by Fig. 2. The free end of the auxiliary blade 6 isformed with an elongated bevel 8, which is adapted'to be used to drawlines between points indicated by markings through the medium of theapertures 5, the square as an entirety being disposed in the mannershown by Fig. 3 for this purpose, so as to bring the edge 8 of the bladeover the work and in coincidence with the bevel or miter marks. Theauxiliary blade 6 is held in immovable or rigid relation to the blade 2,and the instrument as an entirety can be positively relied upon toaccurately square the work.

In addition to the uses of the improved square as set forth theauxiliary blade 6 may be used to continue a mark or indicating-line atopposite sides of a board or piece of timber relatively to a transversemark produced by the aid of the blade 2, as the edge 9 of the auxiliaryblade accurately intersects the adjacent edge of the blade 2, having thescalemarks 4 and apertures 3. The blade 6 always being in the samerelation to the blade 2 will permit the square to be reversed to operatewith opposite sides of a board or piece of timber, and in squaring andmarking strips of comparatively small transverse extent the auxiliaryblade 6 may be used, and-thebroad side of the stock 1 in suchoperationwill be brought to bear against the adjacent side edge of the strip.

The square will befound enceptionallyconvenient for general purposes,and many other advantages will appear from time to time to those usingthe same. It will be understood, of course, that the blades 2 and 6 willbe formed from. suitable tempered metal, as in ordinary try-squareconstructions, and the Width and length of both blades may be varied atwill, as well as the stock 1.

Having thus described the invention, what is claimed as new is 1.Atry-square comprisingastock provided with a main blade, and anauxiliary blade immovably and rigidly held in a plane at a right angleto the main blade and located at the inner edge of the said stock oversaid main blade, the said auxiliary blade having the inner corner of itsfree end formed with an elongated bevel.

2. A try-square comprising a stock provided with a main blade havingscale-marks on the outer edge portion thereof leading to a plu- SAMUELBESS PUGH.
